prathamaṃ ṣaḷaham upayanti, ṣaḷ ahāni bhavanti.
ṣaḍ vā ṛtava, ṛtuśa eva tat saṃvatsaram āpnuvanty,
ṛtuśāṇ saṃvatsare pratitiṣṭhanto yanti
dvitīyaṃ ṣaḷaham upayanti, dvādaśāhāni bhavanti.
dvādaśa vai māsā, māsaśa eva tat saṃvatsaram āpnuvanti,
māsaśaḥ saṃvatsare pratitiṣṭhanto yanti
tṛtīyaṃ ṣaḷaham upayanty, aṣṭādaśāhāni bhavanti.
tāni dvedhā, navānyāni navānyāni.
nava vai prāṇā nava svargā lokāḥ,
prāṇāṃś caiva tat svargāṃs ca lokān āpnuvanti,
prāṇeṣu caiva tat svargeṣu ca lokeṣu pratitiṣṭhanto yanti
caturthaṃ ṣaḷaham upayanti, caturviṃśatir ahāni bhavanti.
caturviṃśatir vā ardhamāsā, ardhamāsaśa eva tat saṃvatsaram āpnuvanty,
ardhamāśaśaḥ saṃvatsare pratitiṣṭhanto yanti
pañcamaṃ ṣaḷaham upayanti, triṃśad ahāni bhavanti.
triṃśadakṣarā vai virāḍ, virāḷ annādyaṃ,
virājam eva tan māsi-māsy abhisampādayanto yanty
annādyākāmāḥ khalu vai sātram āsata.
tad yad virājam māsi-māsy abhisampādayanto yanty,
annādyam eva tan māsi-māsy avarundhānā yanty
asmai ca lokāyāmuṣmai cobhābhyām
